Abstract

Usefulness and clinical availability for surgery efficiency were evaluated by conducting pre-operative planning with a model manufactured by desktop 3D printer by using clavicle CT image. The patient-customized clavicle fracture model was manufactured by desktop 3D printer of FDM wire laminated processing method by converting the CT image into STL file in Open Source DICOM Viewer Osirix. Also, the model of the original shape before damaged was restored and manufactured by Mirror technique based on STL file of not fractured clavicle of the other side by using the symmetry feature of the human body. For the model, the position and size, degree of the fracture was equally printed out. Using the clavicle model directly manufactured with low cost and less time in Department of Radiology is considered to be useful because it can reduce secondary damage during surgery and increase surgery efficiency with Minimal invasive percutaneous plate osteosynthesis(MIPO).

쇄골 CT 영상을 이용하여 보급형 3D 프린터로 제작된 모델로 사전 수술계획을 실시하여 수술효율에 대한 유용성과 임상적 활용가능성을 평가하였다. CT 영상을 Open Source DICOM Viewer Osirix에서 STL 파일로 변환하여 FDM 와이어 척층가공방식의 보급형 3D 프린터로 환자 맞춤형 쇄골 골절 모델을 제작하였다. 또한, 인체의 좌우 대칭 특성을 이용하여 골절되지 않은 반대편 쇄골의 STL 파일을 Mirror 기법으로 손상되기 전 원형의 모델을 복원, 제작하였다. 모델은 골절의 위치와 크기, 정도가 동일하게 출력되었다. 영상의학과에서 적은 비용과 시간으로 직접 제작한 쇄골 모델을 활용하면 수술시 2차 손상을 줄이고, 최소 침습적 피하금속판 골유합술(MIPO)로 수술효율을 높일 수 있어 임상적으로 유용할 것으로 생각된다.
